I have a few dell adapters and laptops. They are all from the same model.

I need a way to identify which charger belongs to which laptop. Also, Can I tell if the adapters are from the same patch?

They all have a similar 23 digit serial number except for the fifth group of digits. They share the following number except for the red underlined digits.

CN-0Y4M8K-72438-37R-09EB-A01

Thanks.
